Ongoing studies into how people make decisions and form opinions are increasingly coming to the discovery that human beings are not the logical, rational creatures we would like to think. Most key decisions are primarily informed not by complex weighing of pros and cons, but by emotional impulse.

Neurological studies are showing that when people debate or discuss topics they are not looking to listen and learn, but to reinforce previously held views. (Like they needed MRI scanners for that - members of any internet forum could have told 'em!) And people are actually predisposed by their brains to hear and note those things which support their own views, and to be 'deaf' to those things which contradict them. So that prat who is ignoring the facts in your debate is in fact predisposed to notice one set of facts, while you're predisposed to notice a different set.

Which brings me to the question: what would it take to make you change you mind? On any topic - you call it: religion, politics, liking or disliking a person, your favourite biscuit... what would make you rethink your opinion and actually face the awesome truth "I could be wrong"?

I'm sure there will be people here so confident in their own beliefs and opinions that they cannot imagine anything would cause them to rethink their view. But I'm challenging people...
